3 Design Information Item Description Comments/Units 1 Project Details Project Author Design Review Proposed Residential Development PT Blink Ltd Structural Engineering Discipline Blink Technology & Associated Vertical Support 2 Background Purpose The purpose of this design brief is to define structural design criteria for our licensed engineer and raise the relevant structural issues and to provide a feedback process with the project design team. Unless superseded by subsequent written advice, structural design will proceed as outlined in this brief. The information in this document shall take precedence over any conflicting information in the general structural, architectural and services drawing notes and specifications. The principal objectives of this brief are: To outline structural system for the building to resist both the vertical (gravity dead and live loads) and lateral loads (wind and earthquake) Project Description To determine appropriate design dead and live loadings for design purposes To determine key parameters for wind and earthquake analysis To advise outstanding information required to undertake structural design The proposed new development will comprise a residential apartment building. The project details are summarised below: The suspended levels will use the PT Blink Flooring System The façade will be the Ritek Walling System Party Walls will be the Ritek Walling System. Internal walls will be light weight non-load bearing partition walls. The lateral bracing system (designed by others) incorporates a reinforced concrete lift & stair shaft. Temporary bracing of the structural steel construction columns will be incorporated in the design to maintain construction stability until the reinforced concrete party walls are complete. 3

9 What Makes Up PT Blink? 9

10 Blink Patented Technology Blink is a technology that uses an innovative design process to deliver patented steel manufactured assemblies under license that delivers significant profits by halving construction time. 10

11 Blink technology is bespoke Blink is complemented by wall systems to produce a structural frame that is very similar to a conventional concrete framed building but much faster. It resists fire in the same way as a concrete frame. It produces acoustic qualities in the same way as a concrete frame. The technology is applied to each building individually 11

12 Simply Put Blink is made up from floor elements and column and wall elements 12

20 Fire Performance Blink is designed to 90/90/90 fire protection in accordance with the Building code of Australia. The floor beam elements are protected by Promat 50 which also protects the post-tensioned strand in the event of a fire. Strand temperature does not exceed 500 Celsius Acoustic Performance Blink conforms to manufactures recommendations for acoustic performance and is dependent on ceiling choice Ritek wall systems conform to acoustic sound compliance and are dependent on system choice 20

25 ComFlor 80 ComFlor provides the steel decking component of PT Blink s patented steel trays. ComFlor has undergone complete fire testing; carried out by Warrington University, UK. Tests have confirmed the top re-entrant dovetail has no effect on the transmission of heat energy through the slab. The effective profile height of 80mm results in a reduced overall slab depth being required for any particular fire rating. Fire ratings of 3 hours are possible with CF 80 (ComFlor 80 Product Guide, S&T Stainless Ltd, 2014, available: content/uploads/comflor/brochures/comflor80brochure.pdf ) Visit our service providers at ComFlor for more information: (ComFlor 80 Product Guide, S&T Stainless Ltd, 2014) 25

26 Fire Specifications for Comflor 80 A 2005 report outlines ComFlor CF80 s fire resistance at the Building test centre. The test was undertaken using Fibre Reinforced concrete with an overall depth of 170mm, achieving 146 minutes fire resistance in this instance, aswell as retaining the capacity to carry load after 167 minutes. Comflor CF80 was tested again at Warringtonfire in 2006, this time using fibre reinforced concrete with a depth of 150mm. In this case CF80 achieved 98 minutes fire resistance, retaining capacity to carry load after 122 minutes. Both tests of Comflor s deck component provide an adequate and safe floor system in case of a fire, providing integrity for periods over 120 minutes. PT Blink uses Comflor CF80 s decking system for its well investigated and adequate fire protection.

28 Comflor 80 Acoustic Rating Comflor 80 has undertaken rigours testing to ensure it meets the minimum acoustic building standards. A 2006 Test by Hedgley Acoustic Consultants matched Comfloors acoustic level to that of the building code New Zealand. The test involved two parts, The First was on Comflor 80 s typical arrangement, with varying Ceiling Cavity Depths that is on offer. The Second part uses the same typical arrangement however with acoustic dampening applied to its cavity, As Seen in the diagram below. (Hegly Acoustic Consultants, 2006, Acoustic Rating of Comflor 80, Environmental & Industrial Noise Control Engineering, Auckland) For Comflor to be acoustically sound, It must meet an STC (Sound Transmission Class) of 55 or above; The results of this test published in the graph below. (Hegly Acoustic Consultants, 2006, Acoustic Rating of Comflor 80, Environmental & Industrial Noise Control Engineering, Auckland) The results show that all Comflor s products can provide an adequate acoustic rating above a depth of 150mm, with 140mm sufficient when using absorption within its ceiling cavity. This depth test shows that Comflor is an acoustically appropriate choice for PT Blink s Patented Steel Decking. 28
